Be it known that I MILTON C. Ellison, e citizen of thelinited States,residing et St. Paul, in the county of Ramsey and State of Minnesota,have invented certein new and useful Improvements in Filled-SackSe\sfingMachines and I do hereby declare the following to be a. full, clear, andexact description oi the invention, such es will enable others skilledin the art to which it apportnins to ineke and use the seme.

My present invention relates to Whet are known es iilled-seck-sewingmachines, and has for its object to improve the seine in the severalparticulars hereinafter noted.

The invention consists of the novel devises end combinations of deviceshereinafter described, sind defined in the claims.

This invention is designed especially as an improvement on the niechineset forth end claimed in iny Letters Patent No. 773,631 issued oi dateNovember 1, 1904, entitled l*"illed-l3egsewing machine.

in the accompanying drawings, Which illus! trete rey invention, likecharacters indioete like ports throughout the several views.

Figure 1 shows the complete sewing-mechine in side elevation. Fig. 2 ise transverse vertical section on the line x2 x* ol Fig. i.V Fig. 3 is a.detail in transverse vertieel seotion epproxiinateiyon the line x3 x73of Fig. 4. 4 is n horizontal section on the line :r4 m4 of l*s ig. 2.Fig. 5 is e detail approximately on the line r :c5 of Fig. 3. Fi 6 is a.horizontal seetion on the line of i 2, some arts Fig. 7 is e orizontasection nteken approximately on the line mi m7 of Fig. 2, Sonie partebeing broken away; and Fig. 8 is a detail in pien illustrating thenienner in which the needle-holder is ivotelly etteehed to theneedle-operating pinger, some parte being broken away.

The freine of the machine is, es shown, inode up of a box-like housing1` which is rigidly sup orted in any suitable wey and is providedp atone side with en outwardly and downwardly turned hollowsupportingbracket 2, having at" itsV depending end atransversely-elongated bearing-heed 3, in

which is mounted a reciprocating needle-serYV Y rying plunger 4. Mountedin suitable been ings within the freine or easing 1 is evertically-disposed counter-shaft 5, which at its upwardly-projectingend above seid easing is provided with o initer-gear 6 and e hendwheel7. The initer-geer 6 meshes with e reiter-gear 8, the hub of which isloosely journeled in e hearing on the upper ortion of the freine 1 endis provided wit i e heli'- eluteh 10. A driving-'shaft 11 is -ournnledin the hub of the gear 8 and in ot er suitable bearings. (Not shown.) Onthe shaft 1 1 is e sliding lialelotch 12, which cooperates with thehalf-clutch 10, being held to rotate with seid shaft by e key 1.3i Thesliding helfoluteh 12 is subject to o shipper-lover '14, Whieh lever,Yes shown, is pivoted et one end to e. lug 15 end is edn. ted to belooked et its free end to e lug 16 y ineens of a. springlstoh 1PZ. Thetivo lugs 15 and 16 are shown es esst integral with the casing 1. Thecoun'- ter-sheft 5 carries two peripheral @eine 1S end 19 sind s. Worin20, the purposes of which will presently ap ear. At its extreme lowerend the shaft 5 is provided with e short throwerenli 21, the crank-pinof which Works in e longitudinal slot 22 of en oscillating loop or bar23, which loop or ber is, es shown, pivoted et one end to e lug 24 onthe interior of the lensing 1, as best shown in Figs. 1, 2, and Ei'.rl`he loop or ber 23 oseille-tes in e horizontel piene and, es shown,carries e supplementel pivotally-attaohed bei' (more fully shown in myseid Letters Patent le. 173,631, of date November 1, 1904,) Vwhich etits Yfree i endnis provided with a depending foot 26, in "which issecured the laterally bent shank of a loo er 27. (See Figs. 2 3, end 6.)The free enY Y Qftheloop oriier' rests upon sind vibretesever e restlate24a.

The thread whic passes through the looper 27 on its wey from the spoolto said loo or passes between the clamping-disks 28 o e tension device2Q; which tension device is, as shown, supported by a. lug 30 on theeosin i' I. This tension device may be of any suite le construction, hetis shown end preferred in States Pet-ent No. ''gliili ofdeteetoberi 1 g,i904, entitled Thread and twine tension device. Furthermore, the threadon its wey to the loo Ver 27 posses through an eye 3l in the free end)of en oscillating sleek-erm 32, which, es shown,is l.riveted to e.bearing 33 Within the easing i' en is subject to the com i9, carried hythe slieft. Y

The needle 34 is direetlyseoured, es shown, by ineens of e set-screw 85to a heed 36, which in turn is pivoted et 37 to the forward end oi' theneedle-carrying plunger 4, as best shown in Figs. 2, 3, 4, and 8. Theneedle heed or holder 36 is adapted to be pivotelly turned the form set'forth and claimed in my United' IOO upward into a vertical position, asshown by dotted lines in Fig. 3, thereby throwing the needle into aposition in which it may be easily threaded. This feature is thereforeimportant. The downward pivotal movement of the head 36 is limited to astraight line with the plunger 4 by cooperating stop-shoulders 36 on thesaid head and plunger. The plun- Urer 4 at its extreme forward end andat its lower portion is formed with a lip 4, which underlies the freeend ofthe head 36,0perates as a stop therefor, and prevents the threadfrom sagging or dropping down too low when the machine is in action,(see Figs. 2 and 3,) at which time the needle is turned. down, as bestshown in said Fig. To lock the head or holder 36 in an operativeposition, a springlatch 38 is secured at the forward end to the plunger4 and at its free end is provided with a lock-lip 38, that normallyoverlies the free end ot said head 36. The numeral 39 indicates aguard-clip on the forward end of the 11eedle-plunger 4, which ovcrlicsthe springd latch 38. In the plunger 4, just at the rear of the rear endofthe head 3G, is a vertical thread-guiding perforation or passage 4t),through which the thread is passed. (See Figs. 2, 3, and 8.)

The thread which. passes through the eye of the needle 34 is indicatedby the dotted lines marked z. This thread, as shown, )asses throughguide-eyes 4l on the supportlng-bracket 2 and between the clampingdisks28 of a tension. device 2Q, shown as supported by a lug 30 on the head 3ot the bearing-bracket 2. This tension device is preferably of the.`same character as the one previously described and designated by thenumerals 28 29. Then the head 3G and the needle 34 are in operative`iositions, they are below the upper plate of the hollow bearinghead 3,and to permit the said parts to be moved pivotally upward a small hingedplate or trap-door 42 is provided. in the upper wall of saidbearing-head 3, just above the said needle and itsiholder. Under itsoutward movement the needle 34 works through a erforation 43 ol awork-guiding flange 44, w lich flange, as shown, is cast integral with aplate 45. The plate 45 spaced apart from a lower plate 46 byspacing-thimbles 47 and the said two plates are rigidly connsfeted toand supported from the lower plate of the casing l by nutted bolts 4S,passed through said three plates and said thimbles. (See Figs. 2, 3, andThe needle-plunger 4 receives its reciprocating movements through abell-crank lever 4Q, the elbow of which'is pivoted at 5() to thebearing-braclwt 2 and one arm ot which is provided with a rollerequippedstud 51, that works in the groove ot' the cam 18. .The depending end ofthe bellcrank 4), as shown, works between a pair of studs 52 on theneedle-plunger 4.

The gathered ends ol' the filled sacks are ,Figs 3 and 4.

'fed to the stitching mechanism by a feedchain, presently to bedescribed, and they are caused to travel through a straight and verynarrow guide-channel formed between. the guide flange or plate 44 and anopposing yielding presser-bar made up of a plurality of sections orblocks 53, located with their ends in close contact and mounted insuitable seats formed in a bar 3, which bar is mounted in the inner edgeof the hollow bearing -head 3. (See particularly Figs. 2, 3, 4, and 5.,)rFliese sections 53 are Jformed with stop-lugs 54, (see Figs 3 and 4,)which engage with the bar 3 tolimit their outward movements. The bar 3is, as shown, formed in two parts, said parts being rigidly united byscrews 3l. The sections 53 are yieldingly )resscd outward by curvedsprings 55, which are seated at one end in the bar 3 and at their outerends )ress against the said. sections and overlap the joints bctween thesame, as best shown in Fig. 5. Each section 53 is provided with a pin53, so positioned as to be engaged by the free end of the spring 55. Aseach section of the chain is pressed inward against the spring by thetravel. of the sack the free end of said spring will engage the pin inthe next adjacent section, thereby moving said section inward, so thatthe chain will always )resent a smooth surface to the sack. The )ar 3 isada ted to be adjusted transversely of the guirlh-channel formed betweenthe guidev(lange 44 and. the yielding bar made up of the sections 53under the action ot screws 56, which work through and are clamped tobearings 57 on the lower plate of the bcaring-hezul 3 by means oflock-nuts 58. At its central portion the bar 3 is eut away to alfordelearance lor the needle 34 and the end of the needie-plunger 4, as bestshown in Fig. 4, and one of the sections 53 is perforated at 53 (seeFig. 3) to ali'ord a passage for the needle 34.

The gathered ends of the filled sack are fed to the stitching mechanismand through the shallow guidechannel already noted by vn'leans ofendless feed-chains 59, to the links of which are secured serratedfeed-clips 6U. This chain runs over three sprockets 61 (i2, and 63, andit is passed between the plates 45 and 46, heretofore noted, as clearlyshown in Figs. and 3. The feed-cli )s `)reject at their serrated. edgesinto the guidIc-c iannel formed between the guide-Bange 44 and theyielding sectional presser-bar 53, as best shown in i That portion ofthe chain which is running from the sprocket 62 to the sprocket G1 bearsat its back against a guidebar 64, which works between the plates 45 and46 and is adapted to be adjusted trans versely of the chain by screws65, swiveled thereto and working through bearingblocks GG on the lowerplate ol' the casing] and locked to said blocks by nuts 67. Said bar 64is provided with transverse slots 64, through IOO ruiter-gear 70, thatmeshes With e ruiter-gear .Y

Y l oi' a short horizontally-disposed she'it T2,

(see Figs. 4 and 7,) which shaft has ay large worin-getti' 73, thatmeshes With the Worin 20 on the vertical shaft 5. In this vvaiT motionis iniperted from the driving-shaft 1i to the vertie el shaft- 5 andfrom thence throught-he connections just desoribed to the feed-chain 59,The sprocket 62 is ioosely journeled on the lower late of the easing 1.The s rocket 63 ioose y ourneled in en edjustab e beering Whieh, asshown, has a threaded stern El-ta, (see Figs. 2 and 4,) that Worksthrough e. fixed bearing on the bese-Harige of the eesing 1 end islocked thereto by nut-s 7 5a. By adjustments of the sprocket 63 thesleek of the chain 59 may be teken up.

The gathering device, which is very similar to that set forth sindclaimed in my seid Let# terel Patent No. 7 7 3,631, of date November 1,1904, but Which involves novel features of improvement, is constructedas follows: A pair of vertically-disposed shafts 76 and 7 7 ere mountedthe former in internel bearings on the casing 1 and the latter inbearings within the vertical portion of the bearingbreoket 2. At theirupper ends these shafts ere provided with reiter-gears 7 S, (see Figs. 2and 7 that mesh with ruiter-gears 79 on e horizontal counter-shaft 80,mounted in suitable bearings on the easing 1 and bearing-bracket 2. Oneend of the shaft 8() projects through the easing l and is rovided withspur-gear 81, that meshes Wit e spurpinion 82, Carried by thedriving-shaft 1l. At their extreme lower ends the vertical shafts 76 end77 are rovided with shortthrow eeoontrios S3. (i ee Figs. 2, 4, and {5.}These .entries operate ou the ends of soeeef gethering-pewls S, whichpewls et their intermediate portions are slotted at and are ulorurned onpins 86, carried by fuleruin-bloeks S7, which hiloruni-l'ilooks, asshown, have threaded stems 8S, that Work through bearings S9 on thelower iienge of the bearing-heed 3 and are clamped thereto by nuts 83a.The gatherin pewls 84 are provided with suppementa spring-extensions U0,which at their free ends Gerry gathering-heads 91. The spring-sections99 are adjustebly secured to the bodies of the pewls 84 b v set-screws92, and eeeh pewl is provided with e tooth 93, thet engages With teethor serretions 94 on the corresponding peWl 84. The set-screws 92 Workthrough slots 95 in the said s ring-seotions 90 and ere screwed into theen s of the pewls 84. As is evident, under the rotary movements of theeceentries rotary movements will be imparted to the ends of thegathering-heads Qi, end the two heads Will act simultaneously to gatherthe mouth of the seek and to feed the seine into the guide-channelbet-Ween the W,Quide-tlenge '14 and yielding ber where the seme will betaken up end eeted upon by Vthe".serreted clips of the feed-(drinn.Vhinder the shove gathering action the seo- Ytions 9D of theathering-psiris yieidingiy ress the engaged portion of the seek, theongitudinal adjustments of the spring-sec tions 91 on the psud-bodiesThe pewlheads 91 may be set for eetio i on the Work et the properpoints, end by shifting the fuleruni-bloeks 87 the are of operativemovementof the seid heeds 91 may be changed so as to vary the amount ofgather Whirh Will be given to the mouth of the seek. When the gatheredportion of the seek is fed through the guide-channel by the serratedclips of the feed-chain, theseotions of the yielding presser'- bar 53Will yield to adept themselves to the varying thielrness et the gatheredmouth of the sack, end it is importent to note that this yielding actiondoes not move laterally the i feed-chain, end hence does not decrease orvary the bite which the serrated edges of the clips normally have uponthe gethered portion of the'seok. Otherwise stated, the serrated edgesel' the feed-clips elwaLxv's have a inexiinuni bite on the seek, Whichis due to the fast that the presser-bar instead of the feed-oheinismounted to yield. The pressure under which the yielding sectionedpresserbar 53 will engage the sack muy be varied by adjustments of thebearing-ber 3a, end the normal projection of the serrated edges of theeed=elips of the feed-chain into the guideehennel iney be varied byadjustments of the ber 64.

It xviii et course be understood that the mechanism ebove described iseepshle of merry modifications Within the. seope of my invention esherein sot forth and eieinied.
